Abstract
The invention discloses a sucrose decolorization method which comprises the following steps: preparing a sucrose water solution, adding a physical adsorbent, regulating the temperature, stirring until the color value of the sucrose solution drops to 40 degree st, filtering, collecting the filtrate, and introducing the filtrate into an ion exchange resin tower to carry out decolorization treatment. The method is simple to operate, and has the advantages of low cost and favorable effect.
Description
Technical field
The present invention relates to sucrose purification techniques field, especially a kind of sucrose decoloring method.
Background technology
Sucrose decolouring is the final stage in cane sugar manufacture production technique, and the colour of its product and the content of impurity, directly affect its marketable value.The decoloring method of sucrose mainly comprises physisorphtion and chemiadsorption.Physisorphtion is to utilize the micropore of physical absorbent inside and space to carry out adsorpting pigment, have advantages of simple to operate, cost is low, but adsorption effect is not ideal enough.Chemiadsorption comprises chemosorbent method and ion-exchange-resin process, utilizes ion-exchange-resin process to decolour to sucrose, and the rate of loss of sucrose is higher.Therefore, be badly in need of a kind of simple, with low cost, good decoloring method of effect.
Summary of the invention
The object of this invention is to provide a kind of sucrose decoloring method, this sucrose decoloring method effect is better.
In order to address the above problem, the technical solution used in the present invention is: this sucrose decoloring method, comprises the following steps:
A, sucrose is added to the water to preparation sucrose solution; Wherein, in every 1 premium on currency, the addition of sucrose is 150 grams～200 grams;
B, add sorbent material, regulating temperature is 30 DEG C～40 DEG C, stirs, and treats that the colour of sucrose solution is down to 40
.st, stops adding sorbent material; Wherein, described sorbent material is gac, diatomite, the one in talcum powder;
C, filtration, collect filtrate, by gained filtrate pass into exchange resin tower decolour processing 1.5 hours～2 hours.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention combines physical adsorption and ion-exchange-resin process sucrose is decoloured, and cost is low, simple, and the sucrose solution colour of gained is lower.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
Embodiment 1
Measure 100 premium on currency, add wherein 20 kilograms of sucrose, stirring and dissolving, then adds 1.8 kilograms of gacs, and regulating temperature is 30 DEG C, stirs, and the colour of sucrose solution is down to 40
